Bioaugmentation is the addition of archaea or bacterial cultures required to speed up the rate of degradation of a contaminant.In a place filled with contamination, microbial life usually finds it
as a place to call home. The biological material that originated in this
contaminated area is able to break down waste, but when the amount of
waste overloads it needs help from a foreign form to increase
performance in breaking down chemicals. Bioaugmentation develops the
biological material in order to smoothly break down certain compounds.
When a microbe is added to the contaminated area, they are able to
improve the biological material’s capability to behave in a manner as to
break down contamination that was already broken up before.
